I did a quick search and found this.

The only reason I read it because it wasn't just all a load of journo bollox, but actually quoting Tory insiders. This adds some weight to what you posted earlier but I reckon Brady may be giving Rishi a heads up on a few letters coming in rather than it being close to the numbers required.
With regards to calling a GE, I agree it's obvious this government is done and it's painful watching them crawl to November.
I think Rishi's made all the wrong choices. I've said it before, he should've pinned his premiership full and square on one nation tory values. Instead he's tried to please the more extremist in his party. I also think it's why he was reluctant to call out the islamophobia and racism.
He's wanted to be Mr Sensible because inherently I think that's what he is, but at the same time he's tried to keep the extremists happy. His stupidity was thinking he could actually get any sort of agreement with them, they're completely unpredictable, completely uncontrollable. It was completely stupid from him. And he's shown himself to be weak, not a leader.
